+Meridian: A new perspective on space and time
+One event. Anywhere. Anytime.

+
+
+Meridian is a geometry-guided video model for authoring new observations of existing events.
+Given a video, choose a new camera path and the source moments to observe. Follow the action from
+another angle, linger on a gesture, or hold an instant while the camera keeps moving.
+Choose where. Choose when.
+
+- Where: design the camera's position, viewing direction, and lens over a shot.
+- When: let the action advance, hold a source moment, or change its pace by retiming the input.
+
+Bullet time is one possibility, not the whole idea. Camera motion and source time can be
+composed into different ways of watching the same event. A single image can also be the starting
+point for a moving view.
+The compound-camera example shows its source and requested path. The ballet examples use still images.

+ A dunk. Source action, revisited from new angles. An edited sequence; dunk completion is source footage.

+
+
+ Play. Hold. Resume. Linger on the splash, then let it continue.
+ |
+
+
+ |
+
+ Compose a camera path. Widen, orbit, slide, approach, retreat—one uncut take.

+ One image. Another viewpoint. A camera move from a single ballet image.

+Method
+
+Matched source, warp, and output frames; the 3D points and cameras are schematic.
+The method is simple: use geometry to show a video model where to look.
+1. Reproject the source. VGGT-Omega estimates depth and source-camera poses. We build colored
+3D points, select the source moments, and project those points through an authored camera path
+into a warped video.
+2. Generate the new view. Meridian, built on MiniMax-H3, takes the source video and warped
+video, aligned to the same source moments, and generates the new shot. Geometry guides the view;
+the video model fills missing regions and refines appearance.
+Preview before generation. Once geometry is available, fast point-cloud rendering makes the
+chosen path visible. Check the framing, viewing direction, and uncovered regions—and adjust the
+camera before running the video model. This inexpensive preview is a useful consequence of making
+camera control explicit.
+Why this matters
+The shift is from generating another scene to choosing another observation of the same event.
+This is the world-model perspective behind Meridian: connect what we see to where and when we
+observe it, grounded in supplied footage rather than unrestricted simulation.
+Unseen regions are generated, not recovered. Geometry errors and large moves—including 360°
+orbits—can destabilize the view. Time edits revisit supplied frames, and separate takes need not
+form a consistent world.
+Try Meridian
+Get started with Meridian.
+Meridian uses MiniMax-H3 with precomputed text embeddings, without loading a text encoder.
+We welcome community work on quantization and CPU offloading toward smaller GPUs, including the
+RTX 4090; those configurations are not yet supported or validated by the provided implementation.
+The release also includes a very basic, vibe-coded Studio demo to illustrate how
+to use the model—not a production editor. It supports multi-key camera paths and real-time 3D
+preview, not real-time video generation.
